Developmental changes in the perception of adult facial age

The author studied children's (aged 5-16 years) and young adults' (aged 18-22 years) perception and use of facial features to discriminate the age of mature adult faces. In Experiment 1, participants rated the age of unaltered and transformed (eyes, nose, eyes and nose, and whole face blurred) adult faces (aged 20-80 years). In Experiment 2, participants ranked facial age sets (aged 20-50, 20-80, and 50-80 years) that had varying combinations of older and younger facial features: eyes, noses, mouths, and base faces. Participants of all ages attended to similar facial features when making judgments about adult facial age, although young children (aged 5-7 years) were less accurate than were older children (aged 9-11 years), adolescents (aged 13-16 years), and young adults when making facial age judgments. Young children were less sensitive to some facial features when making facial age judgments.     

The role of vocabulary ability during visual word recognition in younger and older adults

The role that vocabulary ability plays in adult age differences in word recognition was investigated. In Experiment 1, 44 older adults (ages 61-93 years) were compared with 44 younger adults (ages 18-39 years) on a standard lexical-decision task, with ambiguous words, unambiguous words, and pseudowords serving as stimuli. In Experiment 1, the Wechsler Adult Intelligence Scale-Revised (WAIS-R; D. Wechsler, 1981) vocabulary performance was uncontrolled across the younger and older adults, and the older adults had higher WAIS-R scores. There was no Group x Stimulus interaction. In Experiment 2, the data from the same 44 older adults were compared with data from a new sample of 44 younger adults (ages 18-44). Both groups were then matched on WAIS-R performance. Results revealed a significant Group x Stimulus interaction. Reaction time differences between the younger and older groups on the ambiguous words and unambiguous words were identical. The differences in reaction times for words and pseudowords were greater in the older adults. The importance of vocabulary ability during word recognition and lexical processing is discussed.     

Repeatable Battery for the Assessment of Neuropsychological Status (RBANS): Preliminary Australian normative data

The aim of the present study was to establish demographically adjusted normative data for the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in an Australian context. RBANS data from 172 healthy Australian community dwelling adults enrolled in the “Using our Brains” (UoB) Brain Tissue Donor program between April 2002 and September 2005 were included in this study. The present study group differed from the original North American normative sample on all 12 subtests and five RBANS indices. Education and to a lesser degree age were related to RBANS performance. The present study provides complementary RBANS normative data for clinicians and researchers when interpreting RBANS results for Australian individuals closely matching those reported in this study.     

Adult age differences in attention to semantic context

In three experiments age differences in attention to semantic context were examined. The performance of younger adults (ages 18-29 years) and older adults (ages 60-79 years) on a semantic priming task indicated that both age groups could use information regarding the probability that a prime and target would be related to flexibly anticipate the target category given the prime word (Experiment 1). The timing by which target expectancies were reflected in reaction time performance was delayed for older adults as compared to younger adults, but only when the target was expected to be semantically unrelated to the prime word (Experiment 2). When the target and prime were expected to be semantically related, the time course of priming effects was similar for younger and older adults (Experiment 3). Together the findings indicate that older adults are able to use semantic context and the probability of stimulus relatedness to anticipate target information. Although aging may be associated with a delay in the timing by which controlled expectancies are expressed, these findings argue against an age-related decline in the ability to represent contextual information.     

Spatial distribution of attentional inhibition is not altered in healthy aging

Inhibition of return (IOR) is a phenomenon of attentional orienting that is indexed by slower responses to targets presented at previously attended locations. The purpose of this study was to examine adult age differences in the distribution of IOR to multiple locations. In three experiments, young adults (ages 18–30 years) and older adults (ages 60–87 years) completed an IOR task that varied in the number of simultaneous onset cues (one to seven) and the number of display locations (four or eight). Analyses were conducted to explore whether IOR patterns were most consistent with limited inhibitory resources, with regional distribution of inhibition, or with vector averaging of cues. The IOR effects were most consistent with vector averaging, such that multiple cues initiated a directional gradient of inhibition centered on the average direction of the cues. The IOR patterns varied minimally with age, consistent with the conclusion that older adults and young adults distributed inhibition in a similar manner.     

Hierarchical forms processing in adults and children

Two experiments examined child and adult processing of hierarchical stimuli composed of geometric forms. Adults (ages 18-23 years) and children (ages 7-10 years) performed a forced-choice task gauging similarity between visual stimuli consisting of large geometric objects (global level) composed of small geometric objects (local level). The stimuli spatial arrangement was manipulated to assess child and adult reaction times and predisposition toward local or global form categorization under two distinct trial conditions, with varied density of the local forms comprising the global forms. In Experiment 1, children and adults were presented with common, simple geometric shape hierarchical forms composed of ovals and rectangles. In Experiment 2, adults were presented with hierarchical forms composed of the simple geometric shapes, ovals and rectangles, and additional novel complex geometric shapes, “posts” and “arches.” Results show a clear increase of global processing bias across the age ranges of the individuals in the study, with children at 10 years performing similarly to adults on the simple stimuli. In addition, adults presented with the novel complex geometric shapes showed a significant reduction in global processing bias, indicating that form novelty and complexity lead to additional attention to local features in categorization tasks.     

Genetic Counselors’ Experiences with Adolescent Patients in Prenatal Genetic Counseling

Adolescents comprise a portion of women who present to genetic counselors prenatally. In this study, prenatal genetic counselors (N = 128) were surveyed regarding their perceptions of genetic counseling sessions for adolescent (ages 13–19) and adult (ages 20–34) patients. Counselors perceived differences in methods used to communicate risk information for adolescent versus adult populations. Respondents reported that it is more difficult for adolescents to understand prognostic information than adults. They also noted differences between adult and adolescent populations with respect to the people who typically accompany the patient to the session. Respondents stated that adolescents were accompanied by a parent, friend, or sibling, which differed from adults who reportedly were accompanied by a significant other, father of the pregnancy, or by no one. These findings suggest it is important to recognize that adolescent patients are in a unique stage of their development which may influence a prenatal genetic counseling session.     

Native and cross-language speech sounds: some perceptual processes

Using a developmental approach, two aspects of debate in the speech perception literature were tested, (a) the nature of adult speech processing, the dichotomy being along nonlinguistic versus linguistic lines, and (b) the nature of speech processing by children of different ages, the hypotheses here implying in infancy detector-like processes and at age four "adult-like" speech perception reorganizations. Children ranging in age from 4 up to 18 years discriminated native and foreign speech contrasts. Results confirm the hypotheses for adults. It is clear that different processes are operating at different ages; however, more complex processes may come into play around the ages of 6 to 10 years; boys may use different strategies than girls, and with age, a multiplicity of processes may be concurrently active.     

The Animal = Male Hypothesis: Children's and Adults' Beliefs About the Sex of Non–Sex-Specific Stuffed Animals

The Animal = Male Hypothesis, a variation of Silveira's People = Male Hypothesis (Silveira, 1980), was examined. In Study 1, children ages 3–10 years and adults told stories about a gender-neutral stuffed animal, in Study 2 children ages 5–6 years told stories about 3 neutral and 3 feminine animals, and in Study 3 children ages 5–7 years told stories about 2 neutral animals, observed an adult model use feminine pronouns to refer to an animal, then told stories about 2 more animals. Dependent variables were the pronouns participants used to refer to the animals and what sex they believed the animals were. Results showed strong evidence for an animal = male bias in all 3 studies among children and adults of both sexes on both dependent measures. There were few sex-related differences. The modeling intervention was not successful in reducing the bias.     

Young adult identities and their pathways: a developmental and life course model

Developmental and life course studies of young adult identities have focused on 2 dimensions: subjective age and psychosocial maturity. This study examines the developmental synchrony of these 2 processes. In a longitudinal sample of young adults from Add Health (ages 18-22), a person-centered analysis of indicators of these dimensions identified 4 identity profiles. Two depict early and late patterns of identity; the others represent contrasting types of discordance: pseudo-adult, with subjective age more advanced than maturation level, and anticipatory, with subjective age less advanced than maturational level. The profiles vary by gender, socioeconomic status, and race-ethnicity, as well as by adolescent (ages 12-16) pubertal maturation, psychosocial adjustment, and family context. These results provide support for a more holistic, interdisciplinary understanding of adult identity and show that young adult identities in the Add Health sample follow differentiated paths into the adult years, with largely unknown consequences for the subsequent life course.     

A lifespan database of adult facial stimuli.

Faces constitute a unique and widely used category of stimuli. In spite of their importance, there are few collections of faces for use in research, none of which adequately represent the different ages of faces across the lifespan. This lack of a range of ages has limited the majority of researchers to using predominantly young faces as stimuli even when their hypotheses concern both young and old participants. We describe a database of 575 individual faces ranging from ages 18 to 93. Our database was developed to be more representative of age groups across the lifespan, with a special emphasis on recruiting older adults. The resulting database has faces of 218 adults age 18-29, 76 adults age 30-49, 123 adults age 50-69, and 158 adults age 70 and older. These faces may be acquired for research purposes from http://agingmind.cns.uiuc.edu/facedb/. This will allow researchers interested in using facial stimuli access to a wider age range of adult faces than has previously been available.     

Changes in the parental bond and the well-being of adolescents and young adults

Changes in the parental bond and the well-being of adolescents and young adults were investigated in this longitudinal study among Dutch youngsters aged 12 to 24 years (their ages ranged from 15 to 27 years when they were assessed for the second time three years later, and from 18 to 30 years when assessed for the third time). A total of 1,078 adolescents/young adults (459 males and 619 females) participated. We found a curvilinear pattern in the bond between daughters and their parents. For most of the boys, there was a deterioration in the parental bond during the transition from early to midadolescence, which does not subsequently improve. The general conclusion, however, is that adolescents and young adults maintain a rather good and reasonably stable relationship with their parents. Parents prove to be of lasting importance for the well-being of their growing children. For adult children, the parental bond appears to be as important for their well-being as having a partner or a best friend.

Developmental changes in the recognition and comprehension of facial expression: implications for frontal lobe function.

Children aged 6-15 years old and adults (over 18) were given three tests designed to test perception and comprehension of facial expression. In the first test subjects were given two composite symmetrical faces made from the left or right half of a normal face, the subjects' task being to indicate which composite more closely resembled the original face. In the second test the subjects matched a series of photographs from Life magazine with key photographs of one of six distinct emotions (sad, fear, happy, anger, disgust, surprise). In the third test the subjects chose a key photograph that was appropriate for the face of a faceless character in a cartoon. On the composite faces test the subjects in all groups exhibited a preference for the left visual field composite, implying that all age groups were processing the faces in a similar manner. The results of the other two tests showed that there was an improvement in the perception of facial expression between the ages of 6 and 8 years, little change until about 13 years, and then a second improvement to adult performance at about 14 years. The performance of the 8- to 13-year-old children was similar to that of adult patients with frontal lobe injuries, which could be taken as evidence that the regions of the frontal lobe involved in the performance of these tasks may not be mature until about 14 years of age.     

The acceptance model of intuitive eating: a comparison of women in emerging adulthood, early adulthood, and middle adulthood

The acceptance model of intuitive eating (Avalos & Tylka, 2006) posits that body acceptance by others helps women appreciate their body and resist adopting an observer's perspective of their body, which contribute to their eating intuitively/adaptively. We extended this model by integrating body mass index (BMI) into its structure and investigating it with emerging (ages 18-25 years old, n = 318), early (ages 26-39 years old, n = 238), and middle (ages 40-65 years old, n = 245) adult women. Multiple-group analysis revealed that this model fit the data for all age groups. Body appreciation and resistance to adopt an observer's perspective mediated the body acceptance by others-intuitive eating link. Body acceptance by others mediated the social support-body appreciation and BMI-body appreciation links. Early and middle adult women had stronger negative BMI-body acceptance by others and BMI-intuitive eating relationships and a stronger positive body acceptance by others-body appreciation relationship than emerging adult women. Early adult women had a stronger positive resistance to adopt observer's perspective-body appreciation relationship than emerging and middle adult women.     

Assessing the Impact of a Paid Children,Youth, or Family Worker on Anglican Congregations in England

Drawing on the survey conducted by Christian Research and commissioned by the Youthscape Centre for Research and One Hope, this study examined the impact of a paid children, youth, or family worker on the weekly attendance of 5- to 18-year-old children within 786 Church of England churches with adult attendance ranging from 20 to 250 people. Nearly one-third of these churches had a paid children, youth, or family worker (N?=?259). The data demonstrated that on average the presence of a paid children, youth, or family worker added seven young people between the ages of 5 and 18 years to the total weekly Sunday attendance, after controlling for the weekly adult attendance figures.     

Adults' conceptions of intelligence across the adult life span.

To examine whether young, middle-aged, and older adults view the concept of intelligent person as similar or different during adulthood, 140 adults of various ages rated how likely it would be for individuals of average and exceptional intelligence at 30, 50, and 70 years of age to be engaged in behaviors previously identified by adults as characterizing adult intelligence. Adults perceived more similarity between exceptionally intelligent prototypes of closer ages (i.e., 30 and 50 and 50 and 70). Intelligence was perceived to consist of interest and ability to deal with novelty, everyday competence, and verbal competence--dimensions that were perceived to be differentially important for different-aged prototypes and by individuals of different ages. Participants' conceptions also included the idea that intelligence is malleable and that abilities differentially increase or decrease across the life span.     

Dimensions of affective experience in three age groups.

The dimensions by which adults of differing ages experience emotion were studied by self-administering questionnaires administered to older adults (n = 828) recruited from Elderhostel programs, middle-aged (ages 30-59) children of Elderhostel attenders (n = 231), and young adult (ages 18-29) subjects recruited from college classes or through Elderhostel participants (n = 207). Elders were higher in emotional control, mood stability, and emotional maturity through moderation and leveling of positive affect and lower in surgency, psychophysiological responsiveness, and sensation seeking. These findings are consistent with the hypothesized increase in self-regulatory capacity with age. These cross-sectional differences cannot, however, be distinguished from cohort-related explanations; they require considerable replication across different types of subjects and further characterization of the dimensions in terms of their functions for self-regulation.     

Development of carefulness and quickness observed for a tray-carrying task

The purpose of this study was to investigate the developmental change in performance of groups of children instructed to behave carefully and quickly in a tray-carrying task. The subjects were 69 nonhandicapped children from a kindergarten, ages 3-4 to 6 years, and 20 adult students who volunteered. Subjects were instructed to carry as fast as they could a tray with a glass of water for 3 m without a spill. The amounts of water spilled and the times taken were measured. The amounts of water spilled were hardly different within groups of children of the same ages or between age groups. But the times were different among groups: the younger ones took longer, and the difference in time between tray-carrying and normal walking was greatest for the youngest group. Children could carry the tray as carefully as adults but could not do so quickly. The nature of the representation of the instruction in relation to the behavior of children and the difference in strategy to guarantee carefulness between children and the adults are discussed.
